REMOVABLE RIM ATTCHMENT FOR VEHICLE-WHEELS.

The present invention relates to that class f of vehicle Wheels having a removable rim,

which is attached to the wheel proper by means of an expansible metal ring provided with toggle plates, which are subsequently locked in position.

One of the main objects of the invention is to attach the .rim with the pneumaticwtire in such manner, that it can be easily placed on the Wheel or removed from the saine Without having to take out any bolts or screws.

A further object of the invention is to provide suitable means for locking thetoggle. pla-tes in their closed position.

A further. object is to enable the removable rim to be attached to the side of the wheel proper to facilitate changing the pneumatic tire, as hereinafter more particularly set forth.

` In* the accompanying drawings, in which similar reference letters denote similar parts throughout the several views, Figure l is a plan view` of the Wheel, showing the rim locked in position on the same; Fi 2 and 3 are sections through the rim and felly along theiline A-B and C-D respectively of Fig. l. Fig. l is an elevation of the Wheel, showing thc toggle plates unlocked and FiO. 5 is a cross section taken through opposite sides of the rim and felly of vthe wheel, showing the removable rim attached to the side of the wheel.

The felly band a is made conical on its outer surface and the rim b to which the pneumatic tire is attached in a known manner is placed on to this conical surface. The interior surface of the rim b is advantageously provided with a` number of wedgesh-aped pieces c, which engage the conical exterior surface of the felly band a. The lies opposite to the conical edge the Wedges c rests against when the rim is of the felly band, so that being tightened up on the wheel.y the edge al will be pushed on to the conical surface of the felly band a so that the said rim will be Specification ofvLetters Patent.

supported evenly at both edges, the edge Z engaging the conical part of the felly band, While the opposite of the latter is engaged by the wedges c, as will be readily understood. i

4In o rderto tix the removable rim to the wheel an expansible ring, consisting of several sections -c f and g is provided, the sections e' and j being movable and hinged by means of bolts It It to the fixed section of the ring. The movable sections e and 'f are thus capable of a limited movement inwardlyy toward the center of the wheel. The Whole Vring c f g tits againsathe outer side of the-removable rim or against the outer side of the wedges c of the same and may be pressed on to the same by means of studs i', the opposite or threaded ends of which engage a metal ring Z (Figs. 2 and 3) at the opposite side of the felly, passing through the Wooden felly The two sections c and lt' of the clamping ring are connected up by toggle plates m m, hinged together by means of a hinge-pin oi and hav ing at their adjacent ends open slots o (Fig. 4t), which embrace the stud z'. The open slots of the toggle plates m m provide the advantage that these plates may be brought into and out of engagement With the stud z' Without having to take out the latter. The movable sections e and embrace their studs z' by means of slots 7' which enable a limited movement of the said 'set-tions inwardly when the tojgle plates have been unlocked, also Without the necessity of removing the said studs fi'.

ln order to determine the proper position of the rim o ou the felly baud a, thc former is provided with a metal plate f/ (Fig. l), which is adapted to enter a corresponding opening 1" of the felly. This plate is also admntageously employed for the reception .of the va ve of the pneumatic tire.

The toggle plates m move between two downwardly extending flanges o2 of. a Wedge piece suitably attached to the inside of the rim ZJ. the said togo-le plates being guided between the part t of the disk s and the nut or head of the stud z'. The part s of the disk s t is of greater diameter than i5 and adapted to press against the interior surface of the inner flange v2 of the wedge piece 'v o2. lVhen, therefore. the slotted toggle plates m are removed from'the stud i into the position illustrated in Fig. l and if the stud z is now unscrewed, the part s of face Aof the flange v2 raising or looseningthe' samefrom the conical surface of the i felly band a. On loosening the other studs z' (Fig. 2) a cross pin u presses against the inner surface of the section e f g, also raising Athem and greatly facilitating the re- Vinox-al of the vrim b from the felly band a. A small plate extending downwardly in thev plane of the wheel is attached to the felly and forms an eye y as will be seen from Fig. 3, with which a pin z forming an extension of the hinged pin 'n comes into engagement as the parts are tightened up and thus locks the toggle platesv in their closed pos1tion.

The attachment and detachment of the removable rim is effected in the following manner If the rim is to be taken olfthe wheel, the studs ofithe sections e and f are the same of t-he conical surface of the felly' band and disengaging the pin .a from the eye By means of a Spanner or the like and the bolt head 'w on one of the toggleplates m, the toggle joint is now thrown open in the position shown in Fig. 4. The movable sections e and f are .then moved inwardly, so that the sides of the wedge, against which they act, are disengaged and the upper part of the rim b may be taken olf the felly band and then the lower part detached from the same. If it is desired to fix the rim'on the felly, the plate g at the lower part of the same is first brought into vengagement with the opening r of the felly (Fig. 1) and the whole rim is then pushed over the conical part of the felly band, the sections e and 'f being in their contracted position and the toggle plates m unlocked, as shown in Fig. 4. The sections e and f are then expanded and the slots 0 of the toggle plates adjusted to embrace the stud z',

which is then screwed up, causing the pin a (F ig. 3) to engage the eye y, whereby the parts are locked in position and the rim is firmly secured to the felly band. When the rim b has been tightly fixed to the felly band a a small space a: (Fig. 3) is allowed to remain between the inner surface of the ring e f g and the outer surface of the wooden part Z: of the felly so that in the event of the rim b becoming loosein time, .there will be room for it to be tightened up by means of the studs. The felly band a is of such width in cross-section on comparison with the rim Z1 (Figs. Qiand 3) as to enable the latter to'be tightened up continually on the former as it gets warm.

The removable rim b is provided with an inwardly turned flange 'u' at a point about dianietrically opposite tothe toggle plates m and the rigid or stationary section g is provided with a recess g into which the flange lv may pass. When it is required to fix the rim to the side of the wheel, in order to attach a new pneumatic tire to thesame, as illustrated in Fig. 5, the flange or projection 'v' is inserted into the recess g and the d ouble flange lv lvgis passed over the head of the stud i from the opposite side and the toggle members m are movedoto engage the said stud z', when on tightening up the stud, the rim will be secured temporarily in the position shown in Fig. 5 and the tire may be placed on the same. After this has been done, the rim is again removed and placed upon the felly in the proper position.

I claim as my invention 1. In a vehicle wheel having a removable rim, means for locking said rim in position, comprising a distendi-ble clamping ring attached to the felly of said wheel comprising fixed and movable sections, said movable sections beingconnected by means of slotted toggle plates and studs carried by said felly co-acting with the slots, in said toggle plates.

2. In a vehicle wheel having a removable rim, the combination with said rim of means for attaching the same compris-ing a distendible ring attached to the felly of said wheel having fixed and movable sections studs carried by said felly midway between said movable sections and toggle plates pivoted on said movable sections and to one another adapted vto coact with said studs.

3. In a vehicle wheel having a removable rim, means for locking said rim in position on said wheel, comprising a distendible ring attached to the felly of said wheel, said ring having fixed and movable portions relative to said f-felly, means for connecting said movable portions :omprising slotted toggle plates pivotally secured to said movable portions and to one another, and a stud carried by said felly adapted to coperate with the slots in saidtoggle plates and lock said ring in a distended position.

In testimony whereof I afhx my signature "in the presence of two witnesses.
